TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a mounting structure of an opening frame outer wall formed at an outer wall opening of a building such as a house built by a curtain wall method.
[0002]
[Prior art]
In FIGS. 19A and 19B, generally, an opening frame A for forming an opening W for providing a window, an entrance and the like has an outer wall 20 previously mounted above and below the opening W at a factory. The outer wall panel P is transported to a building site as an outer wall panel P, and the open outer wall panel P is attached to a skeleton. This attachment is performed between the opening frame A and the beam 10 at the upper portion, and between the opening frame A and the beam 10, an upper portion of the foundation (not shown), and a floor plate such as ALC.
[0003]
Conventionally, this attachment is fixed to the body by welding or the like, though not shown. Therefore, when the skeleton is displaced between the beams 10 and the beams 10, the foundation, or a floor plate such as ALC due to an earthquake or the like, the open outer wall panel P cannot follow the displacement, and is damaged or falls off from the skeleton. I was Therefore, various mounting structures have been considered in which the mounting portion between the opening outer wall panel P and the skeleton has a degree of freedom, and this portion is freely movable, and the amount of free movement absorbs the displacement of the skeleton. .
[0004]
An example of this mounting structure will be described.
For example, as shown in FIG. 20, at least on both sides of the upper end of the opening frame A, a fastener 21 is attached to the upper end of the opening frame A by a joint bolt 22 and a nut 12 at a distance H and a bolt 11 and a bolt 11. It is attached with a nut 12. At least on both sides of the lower end of the opening frame A, a through-hole provided at the lower end of the opening frame A is provided with a pin of a fastener fixed to a tip end of the joint bolt 22 or an upper part of the base or a floor plate such as ALC (not shown). Aa is inserted. By attaching the opening frame A to the beam 10 or the like in this manner, the opening outer wall panel P is attached to the skeleton.
[0005]
This mounting is called a locking system, and is mounted with the upper end of the opening frame A pin supported movably upward by a distance H and the lower end locked vertically. Therefore, in this locking method, as shown in FIG. 19C, the opening frame is not affected by the interlayer displacement between the beam 10 on which the opening frame A is attached and the beam 10, the upper part of the foundation, or a floor plate such as ALC. The opening frame A (opening outer wall panel P) is rotatable about one of the pin support portions at the upper end of A, and the outer walls 20 above and below the opening W are integrated with the opening frame A to perform the interlayer displacement. Follow. That is, the mounting portion between the opening frame A and the beam 10 or the like has a degree of freedom, and the amount of free movement of this portion absorbs interlayer displacement, and prevents the outer wall 20 and the opening frame A from being damaged or dropped.
[0006]
[Problems to be solved by the invention]
However, in the above-described conventional technique, the displacement of the outer wall 20 located far from the pin support portion, which is the center of rotation of the opening frame A (opening outer wall panel P), is large. Relative to the outer wall 20 is large, and with respect to a larger interlayer displacement, the interlayer frame cannot be absorbed by the amount of upward movement and vertical movement of the opening frame A, and the outer wall 20 may be damaged or fall off. Sometimes.
[0007]
Similarly, when the width of the outer wall 20 is large, when the pin is rotated around a pin supporting portion on one side of the upper end of the opening frame A (opening outer wall panel P), the displacement of the lower end of the other side is large. The upper wall and the upper wall can not absorb the interlayer displacement, and the outer wall 20 may be damaged or fall off.
[0008]
The present invention has been made in view of the above-described conventional problems, and does not damage or drop the outer wall even when the skeleton is displaced between layers. The upper and lower outer walls of the opening are mounted with a degree of freedom.

It is fixed to the outer wall 20. Also, as shown in FIGS. 17A and 17B, when the outer wall 20 above the opening W is located below the sloped portion of the roof such as the wife's face of the building, the upper side of the outer wall 20 becomes the roof. It becomes the shape which was inclined according to the inclination of.
[0029]
In the above description, as shown in FIGS. 9 and 10, in order to make the upper part of the outer wall 20 movable upward, another fastener 21 is placed at a distance H from the fastener 23 fixed to the back surface of the outer wall 20. The joint bolt 22 and the nut 12 are attached so as to be movable upward by the distance H. As shown in FIG. 18, a through hole 23 b for inserting the fixing bolt 11 into the fastener 23 has a length in the vertical direction. A hole may be provided so as to be movable upward by a distance H. In this case, the upper portion of the outer wall 20 is attached by inserting a bolt 11 into the through hole 23a and the through holes 10a and 7 provided in the beam 10 and the lower cross member 3 and tightening the nut 12.
